GEORGE ELLIOTT MORRISON, F SAYV'ILLE, NEW YORK.

CABBUBETOR.

Application led June 6, 1922, Serial No.A 566,329. Renewed March 14, 1925.

To all whom t may concern.'

Be it known that I, GEORGE ELLIo'rr MOR- RISON, a citizen of the United States, residing at Sayville, Suil'olk County, inthe State of New York, have invented certain new and useful Improvements in Carburetors, of which the following is a full, clear,

and exact specification.

My invention relates to improvements in means for vaporizing volatile liquids, and Athe same has for its object more particularly Yto provide an apparatus by means of which asoline, or other volatile liquids may be etliclently vaporized and mixed with air in order to form a combustible gas.

Further, said invention has for its object to provide an apparatus for producing a combustible gas from gasoline or other volatile liquids, to be used more particularly for heating and lighting purposes. Further, said invention has for its object to provide an apparatus by means of which a uniform temperature may be maintained whereby more eiciently and uniformly to vaporize the volatile liquid.

Further, 'saidinvention has for its object to provide an apparatus in which a plurality of communicating parts are disposed within a suitable container or receptacle and surrounded by a fluid whereby the temperature within the vaporizing chambers of the apparatus may be maintained uniformly at any predetermined temperature.

Further, said invention has for its-object to provide an apparatus comprising a plurality of parts each composed of a series of connected sections to provide a long travel for the liquid and Huid which is to be converted into a combustible gas.-

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings forming part. of this specication- Figure 1 is a central vertical section showing one form of carburetor constructed according to and embodying my said invention;

Fig. 2 is a horizontal section taken essentially on the line 2-2 of- Fig. 1; and

Fig. 3 is a similar view taken essentially on the line 3-3 of Fig. 1. f

disposedla receptacle 11 supported upon the 60 base of said outer receptacle 10 in slightly elevated'position upon feet 12. 13 denotes an air inlet pipe extending throughV the outer casing 10 adjacent to its lower end and communicating at its inner end with the receptacle 11 adjacent to the top thereof.

14, 14 denote two vaporizing chambers arranged one above the other, and each composed of a series of shallow members 15 of circular outline,u and having its top 16 and 70 bottom 16 oppositely inclined and connected at their outer ends by a vertical wall portion 17. Within each member 1-5 is disposed a baiile plate 23 which is dished or f inclined from its center outwardl downwardly and terminates a short distance from the inner side of the wall portions 17 and uniting the to s and bottoms of said sec,

tions. Each o said baflie plates is provided with short feet or projections 24 which serve. 9

to maintain the same in elevated relation with respect to the bottom 16 upon which the same is supported.

Each vaporizing chamber or part 14, 14

is composed of three members 15` which are 85 secured together centrally at their adjacent portionsand provided with circular openings 18 therebetween. The chambers or parts 14, 14 are connected together by a 00 downwardly to a point below the lowermost section 15 of the lower vaporizing chamber or part 14', and thence extending upwardly again and inwardly through the tubular portion 19 connecting the Vaporizing chamber or parts 14, 14", and having its inner end turned downwardlyand extending into a circular baille 21 provided with openngsl22 and secured centrally upon a baille plate 23.

19 denotes a circular baliie arranged upon the bottom of the lowermost member 15 of the upper vaporizing chamber 14', and surrounds the opening therein in order to cause the liquid, which has not been vaporized, to enter the upper end ofthe supplemental connection or pipe 20.

The top 16 of the upper chamber or part 14 is provided with an opening over which is secured a small circular casing having an inwardly inclined bottom 26, and a discharge pipe 25a, and within said casing Y to its lower edge, in line with each of the troughs 29, with a suitable aperture or apertures 3() through which the gasoline or other liquid to be vaporized may pass out and into the troughs 29 upon being delivered to the tubular portion 28 by a supply pipe 31.

At the base of the inner receptacle 11 is provided a pipe 32 which extends outwardy therefrom and through the outer casing 10, and has its outer end provided .with a sultable cock 33.`

The operation of the apparatus is as tollows: The liquid to be vaporized is received through the pipe 31 and ilows into the cup or tubular portion 28 or the spider 27, through the openings 30 therein downwardly through the'troughs 29, and thence downwardly upon the inclined upper surface of the bottom 26 of the small casing 25. The liquid thence continues to flow downwardly adhering to the inner sides o the walls of said parts 14, 14C in the form of a thin vfilm which -gradually and slowly flows downwardly to the lower vaporizing chamber 14. Any excess liquid which is not vaporized ,will be held back by the circular baule 19, and flow into the pipe 2O and upwardly again, and thence into the cup or circular bame 21 provided upon the upper surface of the balile plate or disc 23 of the uppermost member 15 of the lower vaporizing chamber 14, and after passing through the apertures 21 therein flow outwardly over the upper surface of the bams plate 23, and thence downwardly successivel ly through the remaining members 15 of the sul - will be admitted through the ower vaporizing chamber or part 14:.

At the same time, air in suitable quantity, intake pipe 13, and after passing through the receptacle 11 will pass upwardly into the lowermost member oit the lower vaporizing chamber, and after striking the under side of the bale plate 23 will thereof and thence into and through the succeeding members of the lower vaporizinl chamber 1li. After having passed throug the members 15 of the lower,` vaporizingl chamber or part 14', the air will pass through the tubular portion 19 and into the lowermost member 15 of the upper vaporizing chamber or part pass over the outer edges 1li, and thence through said members, in succession, andy finally be received in the closed upper receptacle 25, from which it will pass into the discharge or outlet pipe 25a.

Any condensate or heavy residuum will collect in the lower receptacle 11 from which it ma be withdrawn by the cock 33.

lt will, o course, be understood that the outer receptacle or casing 10 is filled with water or other liquid to about the height indicated by the reference letter a, and may be kept at a suitable or predetermined temperature in order to maintain the temperature within the mixing chambers 14, 14', and receptacle 11 uniform and of such degree as will insure the proper vaporization and mixing of the liquid and Huid passing through the apparatus.

1t is to be noted that in the opera-tion of the carburetor, the lighter or more volatile constituents of the liquid will be vaporized in the upper portion of the upper vaporizing chamber 1d, while the heavier and less volatile constituents of the liquid will be vaporized in the lower portions of the apparatus` and the whole mixed with the necessary quantity of air in the passage thereof through the vaporizing chamber to form the combustible gas of the character desired.

Further, it is to be noted that in the operation of the carburetor any liquid which has not been vaporizcd, or which has bccome cooled in its passage through the upper vaporizing chamber or part 11i will pass into the Supplemental `connection or pipe 20 (which is immersed in the water) and sullciently delayed or detained in its travel to cause the temperature of said liquid to attain the degree required to insure its proper vaporization, and the same then slowly delivered into the upper end of the lower vaporizing chamber part 1t', and subjected to further .vaporizatlon Having thus described my said invention what 1 claim and desire to secure by Letters Patent is:
